An Experimental Study on the Measurement of the Elastic Modulus and Poisson's Ratio Based on the Electrical Measurement Method
Measuring the elastic modulus and Poisson's ratio of materials is an important experimental project in Ex-periments of Mechanics of Materials.In order to enrich the teaching methods and teaching contents of Experiments of Mechanics of Materials,theoretical calculation,finite element simulation technology and electrical measurement testing technology are organically integrated,and the elastic modulus and Poisson's ratio of low-carbon steel are ob-tained by electrical measurement,ABAQUS software simulation and theoretical calculation methods.The results show that simulation results are almost equal to theoretical calculation results,but the error between the experimen-tal measurement results of the electrical measurement method and the results of theoretical calculation is relatively large,which is mainly caused by the poor bonding quality of the resistance strain gauge on the surface of the sample and the inaccurate measurement of the geometric dimension of the sample.
